My sons 7 his dads only recently came into his life after deciding when I was pregnant he didn’t want to have a child. It’s been 6 weeks and I’m the last 3 the agreement is he collects my son and takes him to his family’s home for 2 hours a week, that’s all he asked and he brings him home bed the 2 hours. He lives 10 minutes walking distance away. Before Covid I got my sons hair cut every 4 weeks so iv been keeping on top of it myself every few weeks going over it. His hairs short but still some length. His father had him today and before her left made a comment about my sons hair and I said yeah il give it a trim tonight before his bath. My ex has a shaven head and he said about shaving my sons which I said no to and even text him after and said I’m serious don’t touch his hair and he responded with fine. Well iv just put my son to bed upset because his father took a razor and shaved my child’s hair all off! A razor not even a pair of scissors or shears. When he was dropping my son off he left at the end of the street and walked away couldn’t even face me. My sons begged not to be sent to school this week and he’s only in till Tuesday so im keeping him off. Iv text my ex and said Wdf and a few other choice words and he just said I didn’t think you would mind. My son said he didn’t want to do it but his dad shouted at him and scared him. So here’s my aibu would I be unreasonable if I say for the next while ex is to see my son in my home till he can be a bit of a adult and not do things to spite me. I’d leave the house for a while to give them space. My son said he doesn’t want to go back down yet. His gran my ex’s mum told him off for being upset and said it’s only hair. Yes hair grows back but it’s the fact my sons upset and I told them not to do it.
